If forces acting on an object are unbalanced. true or false

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.

Abeam of electrons moves at right angles to a magnetic field of 4.5 × 10-2 tesla. if the electrons have a velocity of 6.5 × 106 meters/second, what is the force acting on the electrons? the value of q = -1.6 × 10-19 coulombs.
